A statement released by the Suns late last night said the club was aware of an incident involving a "small group" of players, which had abided by club policy and "notified the club of the incident immediately".

"Preliminary investigations indicate that Thai authorities have dealt with the matter and no further action was necessary, however the Gold Coast Suns have high expectations when it comes to player behaviour," the spokesman said.

"The club will discuss the incident with the players concerned when they return from their holiday, where it will be determined if the players have failed to meet the club's expectations."

Brown, an All-Australian defender in 2007 and a member of Hawthorn's 2008 premiership side, was among the the Suns first high-profile player signings, but his season came to an abrupt end when he fractured his pelvis against Geelong last month.

Weller, 19, joined the club from Burnie, Tasmania this year.

Weller Tweeted on Saturday that he was "Off to Thailand with the boys!!".

Later, he wrote: "koh phangan fullmoonparty." As many as 30,000 people attend the party on Ko Phangan, a 50-kilometre boat trip from the tourist island of Koh Samui.
